What AI says about OProfile

OProfile is an open-source system-wide performance profiler for Linux that collects data from hardware performance counters across the entire system or on a per-process basis. It includes tools such as operf for sampling and ocount for raw event counting, enabling profiling of kernel and user-space code (including Java workloads) and correlating samples to symbols. It supports a wide range of CPU architectures and continuously adds support for new processors while addressing compiler and kernel compatibility issues.
